There are many PC users - just like me - who frequently need to extract the audio streams from their video files. If this is also your case, you should give Pazera Free Audio Extractor a try. This free application can act as both an audio extractor and an audio converter. The program supports all major video and audio formats, including AVI, MPEG, WMV, MOV, MP4, FLV, MP3, AAC, AC3, and WAV.
The program's user interface, however, may turn hard to use due to the amount of elements that run together within a single environment. This is especially true for novice users, of course. In the top side of the window, you can create a list with all the source video and/or audio files you want to work with, as the program supports batch processing. Once you do so, you can configure the output folder and decide on the action to take in case the output files already exist.
But the most important aspect to be configured is the output format, of course. The program offers you a good number of presets for all the supported output formats. However, when you choose a preset, you need to load its values manually into the "Audio Settings" panel by clicking on the right button. In this panel, you can change the output format, the bit rate, the sampling frequency, the number of channels, and the output volume level. You can also save your settings as a new preset for further use.
Finally, the program also allows you to trim the extracted audio. You can set a start time offset and either a duration or an end time offset. Besides, you can set an output file size limit, and select the audio track to be extracted from each source file, though the program will not detect the audio tracks present in your source files automatically. You are also allowed to type command-line parameters for FFmpeg, the engine used by the program to extract/convert the audio streams.
